Schoolboy SEO Error

My sites live and die on SEO. For cocktailmaking.co.uk 80% of my traffic is from SEO but for the key cocktail search terms I don't appear in the top ten. For search term "Cocktails" (see image above) I am currently 32nd on Google and for search term "cocktail recipes" I am currently 17th in the US (although top in the UK). I accept this has something to do with my domain having ".co.uk" and being on uk servers but this hasn't hindered me getting #1 for paper airplanes.

So I have been working on a plan to move up from #32 in the search term "cocktails" esp. since as you can see above it is a search term 5x the size of paper airplanes so even a top 10 position would be amazing. My cocktail widget now has helped me get close to 17000 back links. The cocktail widget backlinks amongst those have the anchor text "cocktails". Sadly this hasn't move my position on the term cocktails at all.

So looking at my title and description text I realized I didn't use the word "cocktails" at all, not once. Therefore I have now added the word cocktails to the title and description meta tags and also twice extra in the body of my text... I hope this will see a movement for me in the search results for "cocktails". We shall see, watch this space for reports.
